【问题描述】：

由于以下 n1ql 错误，我无法执行查询：

存储库查询：

public ClientMatrixFactorPopUp findBySupportedValuesAndRequestId(SortedMap supportedValues,Long requestId);

预期 N1QL：

SELECT * FROM b_factor
    WHERE  _class = "com.intervest.price.oxygen.model.ClientMatrixFactorPopUp" and requestId=21
    and supportedValues= { "BAGGAGE_COVER": "0", "CANCELLATION_COVER": "0", "GADGET_COVER": "2", "TRIP_EXCESS": "250" }

堆栈跟踪：

Unable to execute query due to the following n1ql errors: 
{"msg":"Object member missing name or value: (`BAGGAGE_COVER` = 500) - at , \n Object member missing name or value: (`CANCELLATION_COVER` = 500) - at , \n Object member missing name or value:         (`GADGET_COVER` = 1) - at , \n Object member missing name or value: (`TRIP_EXCESS` = 50) - at }","code":3000}

[
  {
    "b_factor": {
      "_class": "com.intervest.price.oxygen.model.ClientMatrixFactorPopUp",
      "requestId": 21,
      results": [...],
      "supportedValues":{
        "BAGGAGE_COVER": "0",
        "CANCELLATION_COVER":"0",
        "GADGET_COVER":"2",
        "TRIP_EXCESS":"250"
      }
    }
  }
]

【解决方案1】：

看起来 spring 数据生成了错误的查询。该错误显示 BAGGAGE_COVER 周围有倒勾。它应该是常量对象。

检查查询生成权。

上面提供的查询将起作用。在 Web 控制台中尝试并验证。

除非确实需要完全匹配，否则应该尝试必填字段而不是对象比较，这样文档就有可以匹配的额外字段。

SELECT * FROM b_factor
WHERE _class = "com.intervest.price.oxygen.model.ClientMatrixFactorPopUp" 
      AND requestId = 21
      AND supportedValues.BAGGAGE_COVER = "0"
      AND supportedValues.CANCELLATION_COVER = "0"
      AND supportedValues.GADGET_COVER = "2"
      AND supportedValues.TRIP_EXCESS = "250";
